Pistol Squat

Move · Resistance Training · Movement, Typed Supps

The leg held out in front is not dead weight — it is the counterbalance that lets you sit that far down at all.

Stage by stage

Set-up (Base of support halves): Standing on one foot adds a frontal-plane balance task, loading the hip abductors to keep the pelvis level throughout.
On the descent (Front leg counterbalances): The extended leg shifts the centre of mass forward, which is what allows the working shin to travel far enough to reach depth.
At the bottom (Ankle range is the gate): Dorsiflexion on the standing side and hamstring length on the extended side usually bind before quadriceps strength does.
Months later (Single-leg control improves): Coordination, range and single-leg strength all build, though balance caps the load below what the quadriceps could take.

Muscles trained

Primary: quads
Secondary: abs, glutes, hip abductors

Intensity

8 METs (Calisthenics (e.g., push ups, sit ups, pull-ups, jumping jacks), vigorous effort).

Time to effect

Weeks: For most people, the first weeks are spent building the ankle mobility, hamstring flexibility, and balance just to reach the bottom position with any control, well before it's really a strength exercise yet.
Months: Once the mobility and balance pieces click, usually around 2 to 3 months of consistent practice, real single-leg quad and glute strength builds quickly since one leg is handling the full bodyweight load every rep.

Common myth

"Pistol squats are mostly a balance trick, not a real strength exercise." In reality: Balance is a genuine prerequisite, but once you can perform one, you're squatting your entire bodyweight on a single leg, a load equivalent to a heavily loaded two-leg squat once you account for the halved base of support. The strength demand on the working leg's quad is substantial; balance is the gatekeeper, not the whole story.
